9905-603 Woodward speed control module

The 9905-603 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

Brand and Model: Woodward 9905-603
Series: 505 Series Digital Governor
Type: Microprocessor-based controller
Purpose: Specifically designed for steam turbines to control their speed and provide overspeed protection.

II. Core Functions

Speed Control:
- 9905-603 Precisely controls the speed of steam turbines by adjusting steam inlet flow.
- Supports single-range or split-range actuators to accommodate turbines of different sizes.
Overspeed Protection:
- Incorporates triple independent overspeed protection logic to ensure rapid shutdown in case of overspeed, preventing equipment damage.
- Provides an overspeed test button for convenient on-site testing of protection functions.
Emergency Shutdown:
- Equipped with an emergency stop button for immediate shutdown in emergency situations.
System Protection:
- - Automatically switches control modes upon sensor failure to ensure uninterrupted system operation.
  - Offers local/remote control priority selection to adapt to different operational scenarios.

Step 5: Start searching for microcontrollers

Now that I have a better understanding of the requirements for the characteristics of microcontrollers, I can start searching for them! A good starting point is

microcontroller suppliers such as Arrow, Avnet, or Future Electronics.

Talk to FAE about your application and requirements, and often they can recommend new components that are both cutting-edge and meet the requirements

Just remember, they may have pressure to promote a certain series of microcontrollers at the moment!

The next best place is the chip supplier you are already familiar with. For example, if you have used certain microchip components in the past and have a

good relationship with suppliers, start searching from their website.

Most chip suppliers have a search engine where you can input your peripheral set, I/O, and power requirements, and then it will narrow down the list of

components that meet the criteria. From this list, engineers can continue to select microcontrollers.

Step 6: Check cost and power limitations

At this point, the selection process has identified several potential candidates. Now is a great opportunity to check power requirements and component costs.

If the device will be powered by batteries and belongs to the mobile type, ensuring that the components have low power consumption is the top priority.

If the components do not meet the power consumption requirements, they should be removed from the list until those that meet the criteria are selected.

Don”t forget to check the unit price of the processor.

Although the wholesale price of many components has stabilized at around $1, if the components are highly specialized or belong to high-end processors,

their unit price may be very important. Don”t forget this key factor
